When Jesus spoke of man’s corrupt, sinful nature He always addressed it in its ultimate result. For example, Jesus never warned us that we must not covet because it might lead to stealing…He said rather, You must not covet because it is stealing. The same goes for all the fleshly appetites and passions that come from our human nature. If you think it – Jesus says you’ve already done it in your heart…from lust to murder. For anytime we allow fantasy to fill our mind instead of truth, our flesh is winning.
